So by having a circle with a diameter of 14 metres it is a sake of calculating the circumference of the patio. This is simply done by (where d = 2r, d is the diameter, and r the radius)
To correctly solve x from the given equation,
3x - 3 = 6x + 1
We first subtract 3x from both sides of the equation and this will give us,
-3 = (6x - 3x) + 1
Simplifying,
-3 = 3x + 1
Then, subtract 1 again from both sides of the equation to give,
-4 = 3x
Lastly, divide both sides by 3 giving us a final answer for x which is x = -4/3.
Answer:
k = 2
Step-by-step explanation:
y = kx
4 = 2k
k = 2 (slope)
Answer:
D. (-2, 1).
Step-by-step explanation:
y = 3x + 7
y = -2x - 3
AS the expressions on the right are both equal to y:
3x + 7 = -2x - 3
3x + 2x = -3 - 7
5x = -10
x = -2
Plug this into the first equation:
y = 3(-2) + 7
y = 1.
Answer:
(-2,1)
Step-by-step explanation:
−x+4y=6
−x+3y=5
We can use elimination by multiplying the second equation by -1
−x+4y=6
x-3y=-5
-----------------
y = 1
Now we can solve for x
x-3y=-5
x - 3(1) = -5
x -3 = -5
Add 3 to each side
x+3-3 = -5+3
x = -2
(-2,1)
